Provide your designs with a dark base using this high quality black cord made with 100% silk. Silk thread is perfect for delicate beads that might be damaged by wire. This card comes with two meters of silk already threaded with an easy-to-use flexible needle. Griffin uses a specific manufacturing process for their silk cord that puts just the right amount of tension on the thread and avoids tangling and knotting. Feel free to browse for other colors and thread sizes.
